Parts List & Cost

Give a simple list of the cost of your project broken down by components. Do not write long stories here.

Design & Implementation

Key Locator

Hardware Design

A in-built Nordic wireless is used for board to board communication.The transceiver used is nRF24L01+ Single Chip 2.4GHz Transceiver. Figure() shows the connection of the transceiver with the SJ One controller.

The boards communicate via 2.4 GHz RP-SMA Duck antennas. Figure() shows the connections of these antennas.

Hardware Interface

The hardware interface is fairly simple. A small 5V battery powers key via its on board 5V pins.The antenna is connected to the SJ One board via its SMA connector.The Nordic wireless has the following connections with the controller. SPI bus is used for communication between them.

Software Design

The software design is divided into two parts:

1) Key Transmitter : A Free-RTOS task is used to detect key press by the user.

2) Key Receiver : A Free-RTOS task is used to detect signal received on the Cane

Implementation

This section includes implementation, but again, not the details, just the high level. For example, you can list the steps it takes to communicate over a sensor, or the steps needed to write a page of memory onto SPI Flash. You can include sub-sections for each of your component implementation.

Testing & Technical Challenges

Describe the challenges of your project. What advise would you give yourself or someone else if your project can be started from scratch again? Make a smooth transition to testing section and described what it took to test your project.

Include sub-sections that list out a problem and solution, such as:

My Issue #1

Discuss the issue and resolution.

Conclusion

Conclude your project here. You can recap your testing and problems. You should address the "so what" part here to indicate what you ultimately learnt from this project. How has this project increased your knowledge?
